# Node.js (MongoDB, JWT, Express, React)

# Tech Stack

## Backend
- **Node.js** with **Express.js**
- **MongoDB** with **Mongoose ODM**
- **JSON Web Tokens (JWT)** for authentication

## Frontend
- **React.js** (for admin panel and user interface)

## Version Control
- **Git**

## Deployment
- **Docker** (optional)

# Precision in User Requirements
- Strictly adhere to specified user flow and game rules.

# Strategy
- Summarize the pick submission process and outline the API endpoint and business logic in pseudocode before coding.

# Strategic Planning with Pseudocode
- Begin each feature with detailed pseudocode.
- **Example**: Provide pseudocode for the weekly scoring process, detailing steps from game result input to entry status updates.

# Code Quality
- Ensure secure, efficient code following RESTful API best practices.
- Implement proper error handling and input validation.

# User Flow
1. Users browse available Pools.
2. Submit up to 3 Requests per Pool.
3. Complete payment for Requests.
4. Admin approves/rejects Requests.
5. Approved Requests become Entries.

# Entry Management
- Each user can have up to 3 Entries per Pool.
- Entries are numbered 1, 2, 3.
- Picks are made and tracked separately for each Entry.

# Pick Management
- Users make Picks for each Entry separately.
- Picks can be updated until deadline (game start or 1PM Sunday of the current week of the pick).

# Scoring and Ranking
- Picks scored after games complete.
- **Win**: Entry moves to next week.
- **Loss**: Entry eliminated from Pool.
- Each Entry ranked separately in Pool standings.

# Results and Standings
- Users view Picks/scores for each Entry separately.
- Pool standings show all Entries (multiple per User possible).
- Pool members can view all Picks after scoring.

# Key Implementation Points
- Limit Requests to 3 per User per Pool.
- Track Requests and Entries separately (numbered 1, 2, 3).
- Implement payment status tracking in Request model.
- Create Entry only after admin approval and payment completion.
- Admin interface for managing and approving Requests.
- Implement state transitions (Request: pending -> approved -> Entry created).
